%X thyroid nodular disease is a highly prevalent condition. most nodules are asymptomatic and only identifiable on images. we have established a relationship between the particular  spoke wheel pattern of thyroid masses and a benign histology. a review of our institutional database of thyroid punctured under ultrasound guidance, histologically studied between 2003 and 2011, was performed. node selection criteria included: mixed /solid, round /oval, surrounded by a halo, with radial structures converging toward a central point, with or without calcifications, and with peripheral vessels along with others oriented toward the center of the thyroid masses. seventy-nine (2.5%) out of 3.204 punctured masses exhibited this sign. average size: 28.3 mm. fifty-eight masses were benign colloid nodules as diagnosed on fna biopsy. remaining masses corresponded to lesion follicular (4 benign, surgically treated; 7 under follow-up, stable; 10 with no information). despite being a rare radiologic finding, the  spoke wheel sign may be another element contributing to ultrasonographic discrimination between benignity and malignancy, especially in large thyroid masses.
